WASHINGTON _ U.S. Sen. Lindsey Graham reiterated Thursday that grounds for impeachment of Donald Trump would be "if the president had collaborated with a foreign government to get an advantage."
Though a newly released whistleblower complaint alleges that Trump, in fact, made such attempts, the South Carolina Republican said he was unconvinced.
"The guy or gal doesn't know crap about what happened," Graham told reporters of the anonymous whistleblower whose allegations have spurred U.S. House Democrats to launch an official impeachment inquiry into the president.
